Calculated High-Temperature Thermopower of Niobium and Molybdenum*
The electron-diffusion thermopower is calculated for Nb and Mo at temperatures 200 K < T < 1600K. The energy dependent conductivity σ(ε) = N(ε)v2(ε)τ(ε) is taken from APW and KKR band calculations. It is assumed that N(ε)τ(ε) is a smooth function of ε. Agreement with experiment for Nb is not good. This is ascribed to failure of the Boltzmann equation.
